UNITED STATES LEVI S. HOGEBOOM AND HENRY B. SMITH, OF THREE RIVERS,MICHIGAN.

BRAN DUSTER AND CLEANER.

SPECIFICATION tanning part of Letters Patent No. 321.108, dated June 30,1885.

Application filed August 2, 1884.

To all whom it may concern: 7

Be it known that we, LEVI S. HOGEBOOM and HENRY B. SMITH, citizens ofthe United States, residing at Three Rivers, in the county 5 of St.Joseph and State of Michigan, haveinvented certain new and usefulimprovements in Bran Dusters and Cleaners; and we do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters or figures of reference marked thereon, which form a partof this specification.

Figure 1 of the drawings is a plan view of our device. Fig. 2 is a sideview of the same. Fig. 3 is a vertical sectional view. Fig. 4 is ahorizontal sectional view taken on line y y,- Fig. 3, and Figs. 4, 5, 6,7, and 8 are detail views. Fig. 9 is a perspective View of one ofthedisintegrating-teeth broken away from one of the disks.

This invention has relation to combined bran dusters and cleaners, andespecially to improvements on the machine for which Letters Patent weregranted to Levi S. Hogeboom and Frank B. Smith, dated June 12, 1883, andnumbered 279,337.

The invention consists in the novel construction and arrangement ofdevices, as will be hereinafter more fully set forth,and particularlypointed out in the claims appended.

In the accompanying drawings, A indicates the legs of the frame, whichare secured to the base-plate or bottom B of the flour-case O.

D represents a spidenframe, which is securedat asufficient distancebeneath the bottom plate, B, to the supporting-legs A. This spider has acentral aperture, a, adapted to receive a step-box, E, which has anannular faceflange, b, to engage the upper face of said spider, andperforations c to receive setscrews, by which said step-box may beprevented from turning in its seat. The step-box Beneath this spider isa hinge-bar-carrying device for adjusting the central vertical shaft,similar to those shown in the patent above referred to.

The base-plate B has a central annular open- 0 ing, d, and an innerannular flange, 6, adapted to support the bottom closing board or disk(No model.)

F of the flour-case. This disk F is provided with a discharge-spout andis securedto the radial arms of the plate B by means of screws or othercommon fastenings, so that when the fastening devices are removed thedisk may be rotated so as to discharge the bran from either side of'themachine. The plateB is also provided on its upper face with a flange, f,to engage the inner lower sides of the boards a, which form the outerwall of the flour-case, and the recesses G, to'seat the lower ends ofthe uprights H, which are arranged at suitable intervals between theadjacent ends of the boards at. These uprights H are longitudinallygrooved on their outer sides to seat the vertical threaded rods I, whichsecure the top and bottom plates to the frame, and are provided withinner longitudinal lateral flanges to close the joints at the meetingends of the boards a, the outer joints being closed by the verticalbatten strips h, which may be secured to the outer face of the uprights.Thus it will be seen that the parts may be readily removed or connected.

K indicates the top annular plate, which is provided with an outerdownwardly-extending marginal flange, m, to engage the outer upper sidesof the boards a, and an inner under flange, n, to engage the inner uppersides of said boards. This plate K is also provided with recesses 0 inthe marginal flange m for the entrance of the uprights and their battenstrips, and with vertical apertures 1", which may carry the shortvertical tubes 8, which provide outlets for the heated air rising in thebran-case.

L indicates the top covering-plate, which is secured to the annularplate K, and closes its annular opening. This plate L is provided with acentral aperture, t, for the passage of the central vertical shaft,carrying a bushing, M. This bushing extends through said aperture t to asufficient distance above its outer surface, and is provided with aflange, a, which engages the outer surface of the plate L around theaperture 75. This flange is cut away to leave a plane surface on oneside, as shown at 1). Against the plane portion of this flange, and tothe outer face of the plate L, is secured a rectangular hopper, N, whichassists in preventing the bushing from turning is also provided on itsunder side with a deep annular flange, w.

1? indicates a non-revolving adjustable disk, which is secured to theunder side of the top plate,'L, over the flange w, by means of setscrewsand vertical threaded studs 2, which pass through perforations in saidtop plate, so that by manipulation of the set-screws the threaded studs,which are made fast to the disk 1?, may be drawn toward or forced awayfrom the under side of the plate L, causing its teeth to engage withgreater or less friction the teeth of a revolving disk on the centralvertical shaft. This disk is also provided with a central aperture forthe passage of the central vertical shaft and the admission of the grainas it falls from the hopper.

R indicates the central vertical shaft, the lower end of which is seatedin the step-box E, arranged in the spider-frame D under the machine.This shaft R is provided near its upper end with a disk, S, which ismade fast to said shaft by a key or locking-screw, and is provided onits upper face with annular se ries of teeth, which occupy the annularinterspaces between the teeth of the upper adj ustable disk, which issecured to the top plate, L. These teeth are peculiar in construction,being tapering from their bases to their extremities, their inner wallsbeing of less height than their outer walls, (see Fig. 9,) and theiropposite sides having vertical transversely-curved grooves a The diskS,which is secured to the central vertical shaft, is provided with anannular marginal extension, b, to engage the lower ends of the outerseries of teeth on the upper adjustable disk. Beneath the disk S, on thecentral vertical shaft, are arranged the usual whippers, c. This shaftis also provided beneath the whippers with radial arms (1, which areslotted transversely near their outer ends. To these arms the fan-bladesand brushes are adjustably secured by setscrews or other suitabledevices.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. The disintegratingdisks having, respectively, an annular series ofteeth which taper from their base, are higher on their outer than theirinner sides, and are provided on opposite sides with vertical circulargrooves, substantially as specified.

2. The combination, with the top plate, L, of the bushing M, having theannular flange provided with perforations to receive secu ringscrews,and having a plane side, 12, and the rectangular feed-hopper secured tothe said plate L against the plane side of the bushingflange, wherebythe latter may be prevented from turning in its seat, substantially asspecified.

3. The combination of the central "ertical shaft, thedisintegrating-disk S, secured to the said shaft by the set-screwpassing transversely through its hub, the top plate, L, the bushing M,the ring having the under annular flange, W, secured to the bushing M,as shown, and the non-revolving disintegrating-disk adjustably connectedto the plate L by threaded bolts and nuts, substantially as specified.

4.. The combination, with the top plate, L, of the upper annular plate,K, having the inner flange, n, the bottom plate, B, having the flange f,the uprights H, recessed on opposite sides, rods I, strips h, and boardsa, adapted to enter the recesses of the said uprights and form theflour-case, substantially as specified.

In testimony whereof we affix our signatures in presence of twowitnesses.
